    TLDR Patients with hidradenitis suppurativa have higher levels of cell-free DNA in their blood.
    This study found that patients with hidradenitis suppurativa (HS) have significantly elevated levels of cell-free DNA in their serum compared to healthy controls. The research involved 20 HS patients, mostly with moderate to severe disease, and 12 healthy individuals. The mean serum level of cell-free DNA in HS patients was 697.4 μg/ml, significantly higher than the 307.8 μg/ml observed in healthy controls (P < 0.0379). Additionally, cell-free DNA levels positively correlated with C-reactive protein (CRP), a marker of inflammation, but not with age or BMI. This suggests that cell-free DNA could be a potential biomarker for HS severity, warranting further investigation in larger studies.

      community The theory that explains everything. Please help me make this big!

      in Research/Science  2447 upvotes 4 years ago
      The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.

      The conversation discusses the side effects of finasteride, including low libido and erectile dysfunction, and the possibility of these effects being permanent, known as post-finasteride syndrome (PFS). Some users report personal experiences with PFS and debate whether the condition is real, with varying opinions on the reversibility of side effects and the role of individual biology.

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      by nkrata in Research  330 upvotes 1 year ago
      FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

      community When are we getting a cure to hair loss?

      in Chat 3 years ago
      Potential treatments for hair loss, including Minoxidil, finasteride, RU58841 and various upcoming pharmaceuticals, gene editing and cloning. It is suggested that a cure, if found, would be highly profitable due to the large number of people affected by hair loss globally.
